ISO uses the term, Integrated Circuit Card (ICC) to encompass all those devices where an integrated circuit is contained within an ISO ID1 identification card. Identification cards — Integrated circuit(s) cards with contacts — Part 1: Physical characteristics. ISO/IEC specifies the physical characteristics of integrated circuit cards with contacts. It applies to identification cards of the ID-1 card type, which.

The fabrication of the card involves a number of processes as shown in figure 4.

The now agreed ISO standards for magnetic stripes resulted in the French chip position and the magnetic stripe being coincident. This part of the card development process is clearly specific to the particular application. So now we can differentiate the different types of ICC by their content.
Most microprocessor ICs operate using the active low reset mode where the IC transfers control to the entry address for the program when the reset signal returns to the high voltage level. The ROM software is provided to the semiconductor supplier who manufactures the chips. The use of the silicon is often referred to as real estate because clearly one wants to get as much as possible into the smallest possible space.
The die mounting and wire bonding processes involve a large number of operations and are therefore quite expensive.
Introduction To Smart Cards. These chips may operate with a supply voltage of 3volts which results in lower current consumption. Unfortunately the French chip position overlaps the ISO magnetic stripe definition. Because in general is 5 or 6 wires are bonded for Smart Card applications this approach is acceptable. Vcc is the supply voltage that drives the chips and is generally 5 volts. The IC module in a Smart Card is like any other electronic component and is not normally expected to be hit with a hammer at regular intervals.
The specification requires this voltage to be discharged 781-1 each of the contacts in both normal 78161- reverse polarity. This means that the line must change direction depending on whether the IC is transmitting or receiving.
Assuming the application is to be placed in the PROM memory of the IC then the next stage in the process is to load the code into the memory. Area 1 is for the number identifying both the card issuer and the card holder.
These commands allow the reading and writing of the PROM memory. The random access memory RAM is a different kettle of fish, this is volatile memory and as soon as the power is removed the data content is lost.
Created inamended in,updated in There is also effectively a minimum order quantity in order to 786-1 this low cost. This will involve the setting of flags in the PROM memory that will inhibit any further changes to be made to the PROM memory except under direct control of the application.
The standard defines the situation after reset whilst allowing the frequency to be selectively changed by means of protocol type 78161. The lower speed is most commonly used to date in Europe but this may change in the future. Your email address will not be published.
7861-1 general however the operating power is supplied to the contactless card electronics by an inductive loop using low frequency electronic magnetic radiation. These commands cover the entire life cycle of the card and therefore some commands may be used before the card has been issued to the cardholder or after the card has expired.
Although the ISO Standard defined eight contacts, only 6 are actually used to communicate with the outside world. An annex is provided that shows how to control the loading of data secure download into the card, by means of verifying the access rights of the loading entity and protection of the transmitted data with secure messaging. The electronic properties and transmission characteristics of the IC card are fundamental to interoperability.
Most contact cards contain a simple integrated circuit although various experiments have taken place using two chips. It should be noted that the thickness dimension does not include any allowance for embossing. Security operation commands are standardized by this criterion.

It ay use biometric methods and standards to achieve personal identification. The standard requires 7816- card to withstand 1, torsions without chip failure or visible cracking of the card. This is in itself an integral and complex process that we shall describe later in more detail. Area 2 is provided for the cardholder identification data such as his name and address.
The task of the designer is therefore concerned with choosing the appropriate product for the particular application. Here a 25uM gold or aluminium wire is bonded to the pads on the chip using ultrasonic or thermo compression bonding. ISO Identification cards – Financial transaction cards In order to pursue our studies further we must note that the cost of the IC at saturation i. The manufacturer of a chip with the user’s ROM code takes on average three months. The transmission protocol must take account of this need to turn the line around.
